WILLIAM J. PALM, or MINNEAPOLIS, MINNESOTA. y

Minneapolis,.in the countyof Hennepinand State of. Minnesota, haveinvented certain new and useful-Improvements Waste- Paper Presses; and Ido hereby declare the Vfollowing "to be a full, clear, and exact'. def'scription of the invention, suchaswill en- 410 able others skilledinthe vk.artto whichitlappertains to make and use the' same..

My invention has for its obj ect -to provide an extremely simple andhighly eiiicijent press especially adapted for use in; pressing andbaling waste paper, but adapted,`never theless, vfor several`analogous-uses. Asis e mg the pivoted wings free-for engagement wellknown, waste paper has considerableV Yso commercial value, and ithasbecome the practice in buildings, institutes, and even ink i privatehomes, to save and sell accumulated waste paper. Wheny placed in sacks,1t v 1s bulky. For this purpose, large and ex'V pansible presses haveusually been employed. My invention provides yan inexpensive press,which, whilef-itmaybemade in-any v desirable size, is, nevertheless,especially Vadapted to bemade" in comparatively small f sizes, such aswill be found convenient' for;

daily use in public buildings, school houses, stores, flats, apartmenthouses, and the like, and even in privatedwellings. In the accompanyingdrawings which'` illustrate the invention, like characters indicate likeparts throughout the several views.

Referring to the drawings: l e Figure 1 is a side elevation of thepress, some vparts being broken away and some parts being sectioned;Fig. 2 is an end elevation of the press.; and,

Fig. 3 is a verticali section'taken on the line w3 w3 of Fig. l.

The press comprises a strong, rectangularbox 1, preferably made of `woodandl provided with a displaceable' side 2. The displaceable side 2, asshown, is connected to the bottom of the boxby hinges 3 and is adaptedto be rigidly locked to the box in a closed' position by suitable lockdevices shown as in the formof hooks 4 pivoted to .the ends of the boxand engageable with eyes or lugs 5 on the end edges of the saiddisplaceableside. The said displaceable side 2 is also preferablyprovided at its ends with laterally projecting brackets or metalWASTE-PAPE?

The. v waste lpapers must,ofscourse, be placed in .the box while the presser plate 7 is removedtherefrom. The presser plate thenbeing placed on top of the waste paper,a person vmay step thereon, and with his weight,com-

press the paper-at the bottom of the box, 'or if desired, a lever may beemployed for this 'y purpose. At any rate, when the lock barsr 8areturned outward, and the presser plate `is' forced downward, the saidpawls will follow,y up their engagement with'the strips 9 and will holdthe presser plate in the lowermost position in'which it'may be forced,so that the waste paper may be held under compres-l sion until it hasset or lost most of its tendency toexpand. In fact, waste paperonceproperly compressed, will expand but very little. When itis desired toremove the presser plate, thefhinged wings ofthe dogs 8 must be turnedbackward.

For binding the compressed ibales of of the box, the Votherends ofthebinding wires are brought outward' through vertical slots `11provided inone of. the sides fof the boX, and preferably formed in thedisplacef` able side 2. The manner ofbinding ofthese Wires may bevaried, Vbutit wouldusually be accomplished as follows: Y ,Y l y Beforethe last pressure is applied to the .paper fin the -boX,.the V:presserplate 7 Awill f,
